Temporary Utilities of Water, Electricity, A/C, Lighting For Construction Site

It will be the Developers responsibility to obtain all necessary approvals from Authorities having jurisdiction for temporary connections to existing infrastructure. Temporary utilities shall be installed in such a manner as not to interfere with permanent construction. The Plot Developer shall provide any temporary holes or sleeves required to install the temporary utilities and shall be responsible to fill the same upon removal of utilities.

Capacitor Banks in Electrical Construction Works

Capacitor banks help to improve the quality of the electrical power and gives us the more efficient operation of the power system. Capacitor banks are inexpensive if we compare the benefits they deliver to overall power system and can be easily installed anywhere on the network. Automatic Power-factor Correction (APFC) Capacitor Banks also known as Shunt Capacitor Banks (SCB) are installed to provide reactive compensation and power factor correction. The use of APFC improve voltage regulation, saves power loss and improve transmission capabilities.

A. Ground Rod:

16 mm diameter stainless steel. Driving head is to be high strength steel. Couplings are to be long length silicon bronze, internally threaded. Threads are to be rolled onto rod to ensure uniform layers of copper and strength. Earth rod is to be complete with non-corrosive couplings, head and bolted connector of sufficient size, and number of bolted clamps to connect all cables terminated thereto.

Medium Voltage Distribution System In Electrical Construction

The work included within this section is for the supply, connection, testing and commissioning of 13.8 KV switch gears, cables, package sub station and all the related accessories necessary for the proper operation of the system as shown and described on drawings, bill of quantity and herein.

The contractor shall coordinate with the other services (trades) involved in the project to insure that the foundation, are suitable for the equipment to be installed.

Installation of Structured Cabling For Voice / Data System In Building Construction

The Contractor shall design, supply and install outlet plates, conduits, trunking, trays, wiring, junction boxes, distribution frames, patch panels, data rack, backbone cables, etc. necessary to form a complete structured system for voice and data cabling within the buildings. Cabling / wiring shall be provided for voice system from patch panel location to each voice/data outlet. Draw wires shall be provided in conduits for future data cabling / wiring by others (if applicable). The installation shall comply with the requirements of ANSI / EIA / TIA-568-1991 as appropriate as well as Local Telecom Authority.

Voice and data outlet plates shall be designed to accept industry standard RJ45 plugs.

Construction Control Guidelines

Construction Control Guidelines of project will help participants to establish right relationship with each other. It explains guidelines and minimum requirements that must be adhered to by developers for the duration of their construction activities. It can be listed as follows:

Electrical Grounding or Earthing Conductors in Building Construction

Buried Earth Conductors:

PVC insulated copper strip conductors or PVC insulated stranded copper cables with cross-section min 70 mm2 or as per earthing calculation.

Earthing Conductors:

PVC insulated copper conductor as described in the Specification for the particular application.

Indoor MV Distribution Panel Boards In Electrical Construction Works

Building projects requires MV Distribution Panel Boards for distribution of power to each utilities. A good electrical distribution network will have proper design, right components, and future load provisions. Space utilization will also be an important factor for maintenance and handling of the equipment. Here we look into what are the features required for design, manufacture, install a MV Distribution panel board including its BIS (IS) standards that serving quality building projects.

Emergency Power Diesel Generating Set In Electrical Construction

This article covers the manufacture, supply, installation, testing and commissioning of 415 volts, 3 ph, 4 wire, Diesel Alternator Set (Diesel Genset). The set shall be mounted on common base frame and complete in all respects including the auxiliary equipment such as battery auxiliary, lube oil pumps, filters, oil storage tank, centrifuge, etc. including piping required for interconnection between the set and the auxiliaries which are mounted separately.

Engineering and Technology

Engineering and Technologies are, in the first instance, simply extensions of the human body, allowing us to overcome the physical limitations with which we are born, and to adapt the natural environment to our own needs. Technologies are inventions of humans that have allowed us to survive, and have enabled our cultures to advance. They are for the most part material objects: tools, for example, are simply detachable additions to the body, the manufacture of which generally distinguishes humans from animals.

Electrical Earthing or Grounding For Metallic Fencing

Compound Demarcation or separations of compounds may use metallic fences sometimes for saving money or aesthetic reasons. Architects and owner of the project decide whether their property protected by compound wall or it needs only fencing. If fencing considered, most cases it will be metallic fence. In the electrical point of view and as a safety measure, metallic fence shall be separately earthed unless they come within 1.8 m of any equipment or structure above the surface of the ground, which is connected to the main earthing system. If the separation of 1.8 m cannot be obtained the fence shall be bonded to the earthing system. Here is how compound fences connecting to the earthing system.

Installation of Audio Intercom System For Building Project

Audio Intercom System being used in high-rise buildings or commercial complexes, provide two way communication from entrances, gates, go-downs, industrial plant rooms and normal doors, to an internal audio handset. It can be used to screen authorized visitors from outside entrance and useful to communicate internally between persons from one room to another room or office spaces. It can also be used to function as effective public announcement system.

Medium Voltage Cables (MV Cables) In Electrical Construction

The contractor shall supply, install, test and commission the 13.8 KV cable network as shown and indicated on the contract documents. Conductor sizes shall be metric as shown, conductor sizes with cross sectional areas smaller than specified will not be accepted.
